It's called UniverSoul Circus, billed as the only African American-owned circus in the world. But you've never been here before and you find yourself wondering, from your seat inside the big top, how a circus can have soul. You understand soul food, with its staples of greens and sweet potatoes, and soul music, such as Aretha Franklin singing 'Respect.' You understand when somebody says, 'You got soul,' and you pump your fist into a black pride salute.
